If chlorophyll a is blocked from absorbing light, what would be the effect on the ability of the plant to do photosynthesis?
The plant will have an enhanced ability to carry out light-dependent reactions
The plant will have a decreased ability to carry out light-dependent reactions
The plant will have an enhanced ability to carry out light-independent reactions
The plant’s ability to carry out photosynthesis will be unchanged, as one of the accessory pigments can fill in for chlorophyll a
